That wouldn't be real solution because to escape ' you still (in most
situations) would need two escape() calls. One for escape ' with ' and
second for rest of characters with \. The best solution is providing
info about context.
Yakov: why so much contexts? for single and double quotes there is only
difference in number of backslashes. Escaping in command line is rather
problem of which character should be escaped (most notably space), not
system of escaping.
I'd like to see only one flag additional and one default:
s - [default - for backward compatibility] "system" escaping with \
v - Vim escaping, ' for ' and possibly some other (future?) differences
m.
