[why]
In some fonts, on in the `patched-fonts/` directory the font information
files contain an explanation why the font is called "Terminess" and not
"Termius" - but the font is neither.
Affected: DroidSansMono and Ubuntu (non mono)
I assume this is a 'I copied the info file over from an existing font
and just change the names' (but the source was unfortunately Terminess).
[how]
Manually remove the paragraph from all files that contain it which but
have another name altogether.
[note]
Not shure if they are autogenerated somehow, with for example
`standardize-and-complete-readmes.sh` ... but a `git grep` showed only
the files that are changed with this PR.

[why]
Some of the patched Mono fonts do not turn up in the font chooser
of Windows CMD and PowerShell (and probably more).
[how]
For some reasons Windows does not identify the fonts as being strictly
monospaced, so they are hidden in that font choosers.
For the monospaced fonts we set now the Panose proportion 'monospaced'.
Windows seems to honor the Panose properties.
It is not clear why we need to set the old Panose props, especially as
Cascadia Code does not (!) set them and is still detected as monospaced.
Anyhow, the way Windows detects if a font is monospaced is a mystery (at
least for me), and this works, so ;-)

[why]
This fixes the Docker image build after changes in 9633b4d moved
PowerlineSymbols.otf into a subdirectory. Previously, the
.dockerignore line for src/glyphs/*.* would exclude any
subdirectories in src/glyphs from being included. Without this
change, a complete font build fails.
[why]
Sometimes fontforge returns None for font.path. That should not be the
case according to specs:
font.path
(readonly) Returns a string containing the name of the file from
which the font was originally read (in this session), or if this
is a new font, returns a made up filename in the current directory
named something like “Untitled1.sfd”. See also font.sfd_path.
This seems to be the case for fonts that do not have a fullname set.
I did not search for nor file any issue at Fontforge.
[how]
In fact we already have the original font file name, and we want to
retain its extension anyhow (if nothing is specified), so we use the
filename that we opened to determine the extension.

Related: #641
[note]
This was the sole usage of font.path.
Has been introduced with commit d8b760aee which looks uncritical.

[why]
When we overwrite a glyph that originally had some special handling, be
it a substitution or position table entry (GPOS/GSUB), that special
handling is usually not appropriate anymore and has to be removed.
If we need special lookup table entries for the new glyph we would have
to add them later anyhow, because we can not rely on their existance.
In Issue #509 it was a ligature entry, that replaced 'f' followed by 'i'
with the 'fi' ligature. The ligature glyph is overwritten by us with a
telephone symbol and the substitution table entry makes no sense
anymore.
[how]
If we overwrite a preexisting codepoint we remove it from all lookup
tables.
Thanks to all other reporters with details.

[why]
When the font file is not existing the message we get is either
unreadable or missleading (at least for normal users).
[how]
Explicitely state why we can not open a font file, at least in the cases
where we can.

The Nerd Font Version is not added to the SFNT Version.
This is also a TODO item in `font-patcher`.
The SFNT-Revision is not updated at all.
[how]
Set the SFNT Version and Revision.

With commit
f7d6fcb5 font-patcher: Allow processing of fonts with fsType set
we added support for fonts with the fsType set. This came up in
issue #686 with font 'Bicubik'.
The solution in that commit uses (modern) textual flags in the
`fontforge` open() method. But they have been only introduced in 2020,
so people using older `fontforge` could not patch anything anymore.
This has been reported in issue #691.
As a quick fix the fsType support has been removed with commit
ab6fa3c5 Reverts part of #687 * the patcher refuses to patch all/most fonts with this flag in the open options
[how]
Revert f7d6fcb5 but use the old fashioned numerical open flags
interface instead.
[note]
The textual open() flags have been introduced into `fontforge`s python
interface with their commit
4a76712f0c
Font Open flag improvements
* Document more Open flags
* Add string tuple interface to python FontOpen API
