Make all the easy updates. There are still quite a few to do, but in
doing these ones I can see that syntastic#makeprg#build() needs to
accept a few more options. Namely:
* "postargs" that appear after the filename
* "tail" that appears after everything - used for things like
redirecting output and piping to grep/sed/etc
* the filename itself - only the java checkers needed this since they
specify the directory of the file to check as well
There are still a few other things to do as well:
* remove the options from the checkers that are now provided by
syntastic#makeprg#build implicitly - i.e. the checker exe and args.
* also, we need to doc the above implicit checker options
Sass partials depend on their parents files for context. This patch disables the
syntax checking for partials by default because of this. To enable checking of
partials let g:syntastic_sass_check_partials = 1. Fixes issue #300.
Only cache the imports when the syntax checker is first loaded. Also,
there was a bug in the logic that was causing the imports to be set to
"" on the second run.
Make the imports var script local since we are not allowing users to
change it.
We dont need to manually hack the bufnr for each entry in the loc list
since that the error output includes a file name.
Ignore the last line of the error message since it seems to always just
be "use --trace for a backtrace"
