Using -v0 works out of the box, but chktex grabs the "v0 format" from
its configuration file:
OutFormat
{
# -v0; silent mode
%f%b%l%b%c%b%n%b%m!n
# -v1; normal mode
...
}
Should the user modify the definition of v0, then the linter would no
longer work. We therefore use "--format" to force the output format.
Also grab the error code so it is correctly displayed.
Closes: #3856
* Fix '-s' to be '-S' when setting 'TabSize=1' for chktex
Fixes#4712Closes#4725
* Check if chktex's -S option is available
* Check chktex version instead of trying -S option
* Fix chktex highlighting wrong column when using tabs instead of spaces
Fixes#723
chktex implemented feature request [1] for allowing setting options from
the command line. Thanks to that we can tell it to treat tab character
as of one space width, i.e. one char. That means, after we translate the
output back to Vim columns, we get correct numbers.
