Support hyphenation helpers in TeX mode

[aspell-helper]

Harald Harders <harders@sf> created a feature request on 2005-07-03 13:01:30 UTC
(Orig. from https://sourceforge.net/p/aspell/feature-requests/41)

LaTeX supports `\-' to declare a position where a word
may be hyphened. aspell should ignore it to test the
whole word as one word (`test\-environment' -->
`testenvironment').

The packages babel.sty as well as (n)german.sty add
some more hyphenation helpers, in particular `"-' and
`""'. Also these should be ignored for looking up words
in the dictionary.

The same applies for the commands that inhibit
ligatures, namely `/' in standard LaTeX and `"|' with
babel.sty.

Now, I have found that this feature should be implemented
already (add-tex-hyphen), but it does not seem to work. Does
it work? And if yes, how?

I second this old feature request. My use case is a bit different (spellchecking XML with in-word breakpoints), but basically it amounts to the same: Being able to suppress certain characters/tokens from the stream to be checked, without having to alter the checked file.

Hi, P.R. #625, should fix this,

Great, skimmed #625, looks like that should work. Will try building locally later. Would it make sense to include `u+00ad` soft hyphen Unicode codepoint in the standard text filter as well (and possibly in the TeX filter)?
