Comment-wrapping filter for BBEdit 10
"""BBEdit UNIX filter that wraps one or more optionally-indented, commented
lines to 79 chars, preserving indentation.
Just select all the lines (in their entirety) the comment spans, and invoke.
Works with #, --, and //-style comments.
For example, this... ::
# Upping this to 10000 makes it 3x faster. 10000 takes 15.936s. 5000 takes 16.303s.
...becomes this::
# Upping this to 10000 makes it 3x faster. 10000 takes 15.936s. 5000
# takes 16.303s.
And this... ::
'PRIMARY-10/14/2008': None, # A special Congressional primary to fill a vacancy that occurred on 8/20/08 in the 22th district
...becomes this::
'PRIMARY-10/14/2008': None, # A special Congressional primary to fill a
# vacancy that occurred on 8/20/08 in the 22th
# district

As it turns out, in BBEdit 10 (at most), Rewrap Quoted Text does this, so you don't need the script.

It does? Now I can't find any evidence of that command.

nice, thanks for sharing.

bbedit does the first use case for just a comment on a line (just tried with v10). for the second case, you can do it in steps, but you need to re-indent & add the comment prefixes... so no, bbedit doesn't really do #2.
