* Remove 'col' from linters where it is hardcoded to 1
When 'col' is 1, the first column will get highlighted for no reason. It
should be 0 (which is the default).
In the scalac linter there was also a check about the outcome of
`stridx`. It would set l:col to 0 if it was -1, and then it uses
`'col': l:col + 1` to convert the outcome of `stridx` to the actual
column number. This will make 'col' equals 1 when there is no match. We
can remove the check because `-1 + 1 = 0`.
* Remove outdated comments about vcol
vcol was added as a default, and the loclists that follow these comments
do not contain 'vcol' anymore
In particular, if we're working with a leex (.xrl) or yecc (.yrl) source
file, erlc would otherwise generate the corresponding .erl file in the
current directory (often the project root), which is generally not what
we want.
Unconditionally writing erlc output to a temporary directory also
matches Flycheck's behavior.
* Add erlc lint for Erlang (#248)
* Ignore certain errors in Erlang .hrl files (#248)
A .hrl file does not need to have a -module definition. Additionally, it
is common to have unused elements in such a file, as the entities will
be used in a file including the header.
* Address change requests to Erlang linter
