matlab-emacs git Merge Request #1: tlc.el new version 1.3, revamped implementation (merged)

1. Make tlc indent by 4 spaces. Previously we were indenting by 2 spaces
   as this was used when we created tlc. Updating to 4 to be consistent
   with matlab-mode, etc.
    2. Don't indent "TLC file guards"
       %if EXISTS(::_FILE_NAME_) == 0
       %assign _FILE_NAME_ = 1
       <tlc file body starts at first column, 0>
       %endif
    3. Don't indent when inside of multi-line comments,
   fixed multi-line comment detection
    4. Various indent fixes
    5. Always align %if/%elseif/%else/%endif statements, even when unbalanced
   "{", "}" language elements exist.
    6. Add support for special "%%{", "%%{{", "%%}", "%%}}", etc. 'indent
   comment shift operators' adjust indentation by 4, 8, -4, -8, etc.
7. Add support for "%%{N}" 'indent comment shift operators' that adjust
   what follows to indent to column N
8. Fix the tlc syntax table to correctly handle single and multiline
   comments
9. Make M-; use single line "%% ..." comments
10. Improved (TAB) indent-region performance by simplify logic
    and only checking for multiline comments when required.
