Details:

I'm using msgmerge (GNU gettext-tools) 0.20.2 on archlinux. Every time I call
msgmerge with --sort-by-file, the commented part will be reversed, causing
unnecessary changes in po file.

Here's a minimal example: Download the attached test.po and test.pot. Run

msgmerge --update --backup=none --sort-by-file test.po test.pot

Observe the commented translations change between "b" "c" "d" "e" and "e" "d"
"c" "b" after each time the command is invoked.

I expect msgmerge not causing these unnecessary changes each time it is
called.

Side note: If there is no source file info, msgmerge will put entries in
reverse order as in pot. I think using same order as in pot make more sense to
me. Or at least always sort them by msgid if file location is the same.
