Updated chktex to 1.7.6.

1.7.6 (2016-09-09), released by Ivan Andrus <darthandrus@gmail.com>

  * Properly copy and free strings.  This caused incorrect file
      reporting in some cases #49000

  * Avoid infinite loop when a regex matches an empty string
  * Fix crash on invalid regular expression
  * Add warnings for $$...$$ and $...$ #47044
  * Update the banner to reflect current bug reporting contacts

1.7.5 (2015-12-07), released by Ivan Andrus <darthandrus@gmail.com>

  * Track whether the previous line ended in a comment #45980
  * Add a few source code environments to VerbEnvir
  * Don't show long line warning if the last line doesn't have a newline #46539
  * Fix deweb's handling of file names #46043,#46042
  * Use the exit status to indicate warnings were found #45979
  * Consider OS X a UNIX

1.7.4 (2015-04-11), released by Ivan Andrus <darthandrus@gmail.com>

  * Fixed undefined behavior (patch from TeXLive)

1.7.3 (2015-04-09), released by Ivan Andrus <darthandrus@gmail.com>

  * Fixed memory leaks and a crashing bug #42813
  * Added ConTeXt \start... \stop... tracking #44517
  * Added DashExcpt list for exceptions to dash rules #42237
  * Support \cite with two optional arguments (biblatex) #44413
  * Removed warning about using \dots instead of .. #40731
      This incorrectly warns about relative paths
  * Removed check for intro since it's common in file names #43013
  * Turn off warning 19 by default #44226
      Warning 19 is about Latin-1 quotes, but gives false positives
      for some utf-8 characters.

1.7.2 (2013-04-17), released by Ivan Andrus <darthandrus@gmail.com>

  * Fixed display bug on platforms where sizeof(int) != sizeof(regoff_t)
  * Warn that .. should be \dots like lacheck does
  * Fixed warnings under clang
  * Incorporated several build related patches from TeX Live

1.7.1 (2012-08-22), released by Ivan Andrus <darthandrus@gmail.com>

  * Improvements for TeX Live and CTAN
  * Fixed bug when checking for interword spacing
  * Added warning when a file has lines that are too long which can cause problems
  * Added ability to suppress user regular expression warnings by "naming" them
  * Added ability to suppress warnings for the rest of the file
  * Allow using PCRE or POSIX ERE or neither (at configure time).
      Regular expressions can be marked as PCRE or POSIX only.
  * Allow () to specify an optional argument in WipeArg to support \cmidrule[](){}
  * Allow regular expressions for Silent keyword, specified in [] for "case insensitive"
  * Added warning about \hline and vertical rules in tabular environments
  * I changed user warnings to be post WipeArg (like they were pre
      1.7.0).  I had changed them in 1.7.0 to be pre WipeArg so that I
      could match things like \label{...}, but this caused many false
      positives by matching in comments, etc.

1.7.0 (2012-05-28), released by Ivan Andrus <darthandrus@gmail.com>

  * Added support for user defined regular expression based warnings

    parenthesis when the parenthesis is at start of line.
  * Update ChkTeX.tex.in to use proper LaTeX2e markup.
  * Update the build machinery a bit.
