Use relative paths in extracted pot file?

[Daniel15]

I'm extracting strings from both C# code (using GetText.NET extractor) and GNOME Blueprint files (which use regular gettext), then using msgcat to combine them into one .pot file. I'm running a command like this to extract the C# strings:

GetText.Extractor -u -as '_' -t /tmp/csharpmessages.pot 

Which results in strings like these:

#: ../../home/daniel/src/WebCamControl/src/WebCamControl.Gtk/MiniWindow.cs:82
msgid ""
"No saved preset. Use the 'Save Preset' menu option or press Ctrl+S to save "
"one."
msgstr ""

#: ../../home/daniel/src/WebCamControl/src/WebCamControl.Gtk/MiniWindow.cs:77
#, csharp-format
msgid "Apply preset \"{0}\""
msgstr ""

...

I'm running GetText.Extractor from the /home/daniel/src/WebCamControl/ directory.

Is there a way to make the paths relative to the current directory rather than the target directory? I'd like the paths to just be src/WebCamControl.Gtk/MiniWindow.cs rather than ../../home/daniel/src/WebCamControl/src/WebCamControl.Gtk/MiniWindow.cs, which would be consistent with how xgettext does it.
