Request for feature

Please, add support for multi-line strings.

This does not work:

_("""
Line 1
Line 2
Line 3
""")

This works:

_("""Line 1 """
"""Line 2"""
"""Line 3""")

And it would be nice if it works in both cases.

This looks tricky to solve. The extraction does work a bit, so it ends up in the generated .pot file when you use rebuild-pot, but the resulting file has errors, for example like this when I try it out in the Poi domain:

$ msgfmt -c locales/Poi.pot 
locales/Poi.pot:22: end-of-line within string
locales/Poi.pot:21: missing 'msgstr' section
locales/Poi.pot:22:5: syntax error
locales/Poi.pot:23: keyword "Line" unknown
locales/Poi.pot:24: keyword "Line" unknown
locales/Poi.pot:26: end-of-line within string
msgfmt: found 6 fatal errors

That is because this bad syntax is generated:

msgid "
Line 1
Line 2
Line 3
"
msgstr ""

This also means that the extracted msgid does not end up in the .po files.

Apparently the correct output would be:

msgid ""
"\n"
"Line 1\n"
"Line 2\n"
"Line 3\n"
msgstr ""

This may be fixable in extract.py or pygettext.py. Pull requests are welcome.

Workaround: use a one-line msgid and specify the multi-line text as the default, like in ad85bed.
