Subject: Mark more strings for translation in Python scripts
X-Git-Tag: release/2.11.40-1~3^2~20^2~5
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=35701c5754b410746d5eb83f4a28b5df92318a0d;p=lilypond.git

Mark more strings for translation in Python scripts

* mark all user messages for translation in musicxml2ly
(edit some strings too)
* uniformize case of first character
* mark convert-ly rules for translation, and clean up these strings
a lot
