Hi Артур,
That's because Vim's "branch" ("\&") in a pattern is not part of POSIX
regular expressions (neither basic, nor extended).
man ex
REGULAR EXPRESSIONS
ex/vi supports regular expressions (REs), as documented in re_format(7),
for line addresses, as the first part of the ex substitute, global and v
commands, and in search patterns. Basic regular expressions (BREs) are
enabled by default; extended regular expressions (EREs) are used if the
extended option is enabled. The use of regular expressions can be
largely disabled using the magic option.
Drop it and you'll have a BRE :^)
Regards,
Raf
