Re^2: trimming space from both sides of a string

It seems likely (without benchmarking) that those two substitutions (s/^\s.*//; s/\s.*$//;) are very efficient at removing leading and trailing white space. However the side effect of removing everything if there is leading or trailing white space may be too much of a price to pay for "efficiency"!

True laziness is hard work

oh! Right! No dot in there. `s/^\s//; s/\s$//;` instead of course. `s/^\s+//; s/\s+$//;` should work as well.	[reply] [d/l] [select]

`s/^\s+//; s/\s+$//;` works better than `s/^\s//; s/\s$//;`.	[reply] [d/l] [select]
