Using xgettext has a few benefits compared to the previous perl extraction
approach. The xgettext utility is able to properly distinguish commented
from uncommented code and it is able handle concatenated constant
expressions such as `_("Some " + "string")`.
A further benefit is the ability to extract translations with disambiguation
contexts and plural translation calls.

The scanning routine has caused unnecessary changes to the .po files
if a string has been found in multiple files and those files have been
found in different order than the previous time.
Sort the location annotations to avoid unnecessary changes to the .po files.
(sort is alphabetic, so the line numbers are also sorted alphabetically)

Experienced with this perl version:
"This is perl, v5.8.8 built for i386-linux"
Fix it by undefining the 'sub' variable if it is an
empty string.
