the first and only mention of & as a wildcard in the full versions.txt is as follows:

Code:
73.Can now use & character as a wildcard one word match, eg.

     &     lines would &
     These lines would match


though if you try the following example:

Code:
//if (a& iswm abc) echo this shouldn't echo


it echoes. this appears to contradict the description since & is matching 'bc' which isn't a word in 'abc'
