I've updated the attachment to post #1 to add the `My 24 line spacing values` patch. Here it is if you want to copy and paste instead of downloading the attachment again:

`My 24 line spacing values` for 4.6.9960 (paste into libnickel.so.1.0.0.patch)

Spoiler:

<Patch>
patch_name = `My 24 line spacing values` 
patch_enable = `no`
# patch_group = `Line spacing values alternatives`
#
## This patch changes the values on the line spacing adjustment slider,
## increasing the number of spacing options from 15 to 24, and allowing
## much narrower spacing values to be set.

# The first 14 replacement values above should allow the line spacing to be
# adjusted in increments of one pixel when using a medium sized font on a high
# resolution device. If you use a smaller font size and/or a lower resolution
# device you might find that increasing the slider one step at a time doesn't
# always result in a line spacing increase at each step. In that case, you
# might want to use replacement values that are not quite so close together.
#
# For example: (I use these values on my 758x1024 Glo)
#
#  0.7 0.725 0.75 0.775 0.8 0.825 0.85 0.875 0.9 0.925 0.95 0.975 1.0 1.025 ...
#
# or: (these might better suit the 600x800 Touch)
#
#  0.6 0.633 0.667 0.7 0.733 0.767 0.8 0.833 0.867 9.0 9.33 9.67 1.0 1.025 ...
