vi: allow delimiter in ':s' to be escaped

When regular expressions are allowed in search commands it becomes
possible to escape the delimiter in search/replace commands.  For
example, this command will replace '/abc' with '/abc/':

   :s/\/abc/\/abc\//g

The code to split the command into 'find' and 'replace' strings
should allow for this possibility.

VI_REGEX_SEARCH isn't enabled by default.  When it is:

function                                             old     new   delta
strchr_backslash                                       -      38     +38
colon                                               4378    4373      -5
