Re: [] or | ?

[Jean-Christophe Helary]

Thank you solak, that's exactly the issue. We found about it when I was 
exploring ways to fix an "open text path with emacs" kind of service, at the 
same time as I noticed the equivalent service in BBEdit was not working as 
expected. Interesting how fixing a seemingly small issue can lead to finding 
deep implementation bugs...

Oh, it is definitely the case that if the pattern in question is then 
concatenated into a more complex pattern, then '[ab]' is equivalent to 
'(a|b)' but not to 'a|b'.

Consider that the function to which the pattern is given might then be 
searching for, something like '^(?:(.*?)[ab])*(.*)$' or 
'^(?:(.*?)a|b)*(.*)$' to populate \1 \2 … with the various substrings of 
the long string with delimiters.

I suggest that this indicates a bug in the split-string function, which 
ought to wrap the delimiter pattern so that it tells the RE engine to match 
'^(?:(.*?)(?:a|b))*(.*)$' instead.

Re: hide sidebar results in unwanted window resize

[solak]

Thanks from me also for the AppleScript, though I still suggest that this 
should be the default behavior.
