The effect of this patch is the same as "forcing" the conversion to the
ligatures in lib/unicodesymbols (see below).
+2 traditional TeX constructs for em- and en-dash in the *.tex file
* familiar look
* no change to line breaking behaviour
+1 simple, no preamble code required
-1 hard to configure (a macro can be redefined, a font ligature not).
-0 inserting ----- stays as difficult as inserting 5 spaces in a row
(needs a "literal" layout).
+1 index sorting problem solved (Ticket #10490)
with the differences
-1 additional code vs. 2 changed lines.
-2 hard-coded replacements:
* inconsistent handling of Unicode characters
(Paragraph.cpp vs. lib/unicodesymbols)
* not configurable (not even by a power user).
I recommend the lib/unicodesymbols patch below as simple fix for the line
wrapping problem.
This would still not enable input of a line of hyphen characters in
"normal" text, though but maybe pressing CTRL-M (or CTRL-P C) *before*
the input is an acceptable workaround.
With an LFUN instead of the hard-coded binding to "-" for the input
convention, a user can turn off the auto-dash feature without need for
an new special setting. Then, also the input of ----------------- becomes
easy --- at the expense of more complicated input of the dashes.
