Yes - I agree it's obvious when you know that the comment is stripped
upstream...

Approved. Thanks for fixing.

Given the number of regressions/failures we've seen in this area,
I really thought we should add a test for this, so I created
the attached patch.  I will commit after you have committed yours.

gdb/testsuite/

        Test indented comment in file being sourced.
        * commands.exp: Test indented comment in file being sourced.

Tested on x86_64-linux.  Fails miserably without Jan's patch.
