Fini Jastrow 7ef696a8b4 font-patcher: Fix: Fix more 'Nerd Font Mono' too wide 
[why]
With commit
  99c260831  font-patcher: Fix more 'Nerd Font Mono' too wide

the glyphs 'ij' and 'IJ' are exempted from the advance width
calculation, because some fonts (i.e. Overpass Mono) defines them as two
cell wide glyphs (Hello? 'Mono'?)

For some obscure reason it was 'IJ' and 'J circumflex' that were
exempt, not 'ij'.

[how]
Exempt correct code.

Fixes: #703

# Most glyphs we want to maximize (individually) during the scale
# However, there are some that need to be small or stay relative in
# size to each other.
# The glyph-specific behavior can be given as ScaleRules in the patch-set.
#
# ScaleRules can contain two different kind of rules (possibly in parallel):
# - ScaleGlyph:
# Here one specific glyph is used as 'scale blueprint'. Other glyphs are
# scaled by the same factor as this glyph. This is useful if you have one
# 'biggest' glyph and all others should stay relatively in size.
# Shifting in addition to scaling can be selected too (see below).
# - ScaleGroups:
# Here you specify a group of glyphs that should be handled together
# with the same scaling and shifting. The basis for it is a 'combined
# bounding box' of all glyphs in that group. All glyphs are handled as
# if they fill that combined bounding box.
#
# The ScaleGlyph method: You set 'ScaleGlyph' to the unicode of the reference glyph.
# Note that there can be only one per patch-set.
# Additionally you set 'GlyphsToScale' that contains all the glyphs that shall be
# handled (scaled) like the reference glyph.
# It is a List of: ((glyph code) or (tuple of two glyph codes that form a closed range))
# 'GlyphsToScale': [
# 0x0100, 0x0300, 0x0400, # The single glyphs 0x0100, 0x0300, and 0x0400
# (0x0200, 0x0210), # All glyphs 0x0200 to 0x0210 including both 0x0200 and 0x0210
# ]}
# If you want to not only scale but also shift as the refenerce glyph you give the
# data as 'GlyphsToScale+'. Note that only one set is used and the plus version is preferred.
#
# For the ScaleGroup method you define any number groups of glyphs and each group is
# handled separately. The combined bounding box of all glyphs in the group is determined
# and based on that the scale and shift for all the glyphs in the group.
# You define the groups as value of 'ScaleGroups'.
# It is a List of: ((lists of glyph codes) or (ranges of glyph codes))
# 'ScaleGroups': [
# [0x0100, 0x0300, 0x0400], # One group consists of glyphs 0x0100, 0x0300, and 0x0400
# range(0x0200, 0x0210 + 1), # Another group contains glyphs 0x0200 to 0x0210 incl.
#
# Note the subtle differences: tuple vs. range; closed vs open range; etc
# See prepareScaleRules() for some more details.
# For historic reasons ScaleGroups is sometimes called 'new method' and ScaleGlyph 'old'.
# The codepoints mentioned here are symbol-font-codepoints.
