Error highlighting with vim-LanguageTool may fail

[matze-dd]

For highlighting of errors in the source text buffer, vim-LanguageTool does not directly use the error location returned by the proofreader. Instead, it tries to identify the reported problematic text part at the line given by the proofreader (application of Vim's matchadd()). This fails for

\newcommand\books{books}
A \books{} are interesting.

The mistake 'A books' is correctly reported for line 2, but it cannot be highlighted in the source text buffer.
