No, that's too lax.  In one of my documents I actually do have an \iface
macro which has nothing to with "if".

What I basically had in mind was having two variables
`TeX-begin-macro-list' and `TeX-end-macro-list'.  From those begin/end
regexes could be created using `regexp-opt' and used analogously to
`LaTeX-begin-regexp'/`LaTeX-end-regexp'.

This has the benefit that a hypothetical ifplatform.el style simply can
add \ifwindows and friends to the `TeX-begin-macro-list' and indentation
should just work.

By default, `TeX-begin-macro-list' should contain all the standard TeX
if variations: if, ifx, ifnum, ifodd, ifdim, iftrue, iffalse, ....  Then
the begin regex would be computed by (concat "\\\\" (regexp-opt
TeX-begin-macro-list) "\\b").  Note that "\\\\if\\b" also matches
"address@hidden" solving your original issue.

Likewise, `TeX-end-macro-list' would contain "else" and "fi".

Does that make sense?
