**The functionality of the package 'Matchit' that is shipped with vim 8.2 is broken for .tex files.

**Minimal example:
The file test.tex contains the following text:

(hello)

**Expected behavior: when the cursor is placed on the '(' character, a keyboard press of the '%' button should take the cursor to the ')' character.

**Faulty behavior: instead, an error message pops up, saying:

Error detected while processing function matchit#Match_wrapper[161]..<SNR>65_Par
seSkip:
line 10:
E488: Trailing characters: . strpart(skip,2). "'"
Error detected while processing function matchit#Match_wrapper:
line 174:
E121: Undefined variable: r
line 176:
E121: Undefined variable: r

**Possible solution: replace the file /usr/share/vim/vim82/pack/dist/opt/matchit/autoload/matchit.vim with the newest version of matchit.vim (commit 9c1c78e, https://github.com/chrisbra/matchit/blob/master/autoload/matchit.vim)
