#1997 Syntaxis error in Batch scripts

[Juan Mier]

Description of the Issue
When coding batch scripts, the command IF's arguments will be taken as mistakes or misplaced if between brackets when in reality it works perfectly and sometimes is mandatory.

Steps to Reproduce the Issue
Select "Batch".
Input "if [whatever] (argument & argument) ELSE (argument)
Expected Behavior
The first argument in the bracket should be marked as a normal command.

Actual Behavior
Sometimes is marked as a mistake, others it marks the command's argument as the actual command.

Debug Information

Note that in the screenshot, 'echo' is marked differently than 'goto'.

http://prntscr.com/id6tsf
In this screenshot, Notepad++ takes 'ELSE' as a command and completely skips the other arguments.

In both cases, the script is working as expected with no error messages whatsoever.

Its helpful to include the text of an example as transcribing from an image takes time and may be inaccurate.

The batch lexer is too simple for these sorts of expressions. It has no knowledge of how '(' can be used in batch files.

Its possible that someone will come forward to work on these sorts of issues but I won't be working on this myself as I do not write complex batch files.
