Thanks for your try. Right, two search()es are much effort just for
getting the contents of a single match.
I first tried to use
//^M
y//e^M
in a loop, but this fails for matches of length 1.
Your function does it right.
Since in most cases I have a pattern that matches on a single line and
I only want matches for the last search pattern, I'll go with this:
func! CollectMatches()
let matches = []
let patq = substitute(@/, "'", "''", "g")
exec 'sil g//call substitute(getline("."),'''.patq
\.''', "\\=add(matches, submatch(0))", "g")'
return matches
endfunc
