Fini Jastrow e957f9f217 gotta-patch-em-all: Fix filename parsing
[why]
The find predicate (e.g. -iname) and predicate parameter (the actual
pattern) are in one variable and will be handed over to find as one
parameter instead of two.

How could this ever work?

[how]
Pass predicate mode and predicate parameter as two shell variables.

# The optional first argument to this script is a filter for the fonts to patch.
# All font files that start with that filter (and are ttf or otf files) will
# be processed only.
# Example ./gotta-patch-em-all-font-patcher\!.sh "iosevka"
# Process all font files that start with "iosevka"
# If the argument starts with a '/' all font files in a directory that matches
# the filter are processed only.
# Example ./gotta-patch-em-all-font-patcher\!.sh "/iosevka"
# Process all font files that are in directories that start with "iosevka"
# for executing script to rebuild JUST the readmes:
# ./gotta-patch-em-all-font-patcher\!.sh "" info
