Subject: py-compile: handle filenames with whitespace
X-Git-Tag: v1.16i~123
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=8a913c268e462a89509726dfeba2cba5e406793c;p=thirdparty%2Fautomake.git

py-compile: handle filenames with whitespace

The list of files is put into a string and then split on whitespace.
Fix the way the list of files are passed to the compile script.

* lib/py-compile: Pass files as arguments, not as a string.
* t/py-compile-files.sh: New test.
