When I use <S-F5> to change the latex environment, I get two backslashes: \\begin{changed} … \\end{changed}. It seems that the variables 'first' and 'second' (envmacros.vim: s:change) are not evaluated as if they were strings. (VIM 7.3.260). I atach a patch to fix this.

    Change Environment: only one backslash with \begin{…} and \end{…}

    Surprised it works for you. To me, it seems that the vim documentation indicates that doubling is necessary in the given examples, which use double quotes. Yet double and singe quotes have different semantics. I get:

    File:
    aabbcc

    Commands:
    :s/a/\='\\'/g
    :s/c/\="\\"/g

    Result:
    \\\\bb\\

    (I.e. doubling needed for double but not for single quotes.)

    Hence, I wonder why the current version works for you, considering that it assigns first and second expressions with single (not doble quotes), in which the backslash need not be doubled.

    This exact problem is happening to me as well. Reproducible in both Vim 7.3 (Apple's) and 7.3.744 (compiled via Homebrew) on Mac OS X 10.8.2.

    VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Jun 20 2012 13:16:02)

    MacOS X (unix) version
    Included patches: 1-744

    Additionally, when I choose \[ or $$, it becomes \begin{\[} and \begin{$$}. I'll share my rough patch for this one as well. https://gist.github.com/4283455
