23.2; cperl-uncomment-region is NOT an inverse of cperl-comment-region |

If I have a buffer in CPerl mode containing
#!/usr/bin/perl
use strict;
use warnings;
cperl-comment-region on the whole buffer makes
# #!/usr/bin/perl
# use strict;
# use warnings;
cperl-uncomment-region makes
#!/usr/bin/perl
use strict;
use warnings;
There's now an extra space at the start of the
line. cperl-uncomment-region is essentially the same as
(comment-region beg end -1)
This produces the erroneous behavior. (uncomment-region beg end) does
work, though. Thus, there may be a bug in (comment-region)
