tex-latexdiff{,-doc}: update to 1.3.2

# latexdiff
## API adaptions:
- latexdiff now completes with exit code 0 after --help or --version command
## New features / feature extensions
- extend CUSTOMDIFCMD related postprocessing to deal properly with multiline
  commands, or a sequence of several commands in the same line
- support for additional macros from import package (\import, \inputfrom,
  \includefrom, \subimport, \subinputfrom, \subincludefrom).
- replace default driver dvips->pdftex
## Bug fixes:
- fix bug by replacing \hspace{0pt} after \mbox{..} auxiliary commands with \hskip0pt
  (IMPORTANT as old way apparently breaks latexdiff output under default setting
    with recent versions pdflatex)
- fix issue affecting proper markup of text commands which are not also safe cmds and
  have multiple arguments
- fix issue by adding \eqref (amsmath package) to the list of safe commands
- fix bug reported in mangled verbatim line environment
- more ways to process \frac correctly with atomic arguments.
- fix a bug in biblatex mode, which prevented proper processing of modified \textcite
- -h string fix: add -driver option

# latexdiff-vc
## Bug fixes:
- when setting config variables with the command lines it is now possible to use
  quotes to include spaces in the value, e.g. `-c LATEX="pdflatex --shell-escape"`
- as --only-changes is not compatible with graphics markup, --graphics-markup=none
  is now set automatically when this option is selected
- when --pdf or --postscript is select, then replace tildes in version names with
  underscores in output file (e.g. diffHEAD_1 instead of diff HEAD~1. This is
  necessary because pdflatex strips ~n strings at the end of the filename, when
  generating output file names

# latexrevise
## New features
- Introduce option -r / --replace which removes markup of the form
  \replaced{new text}{old text} in the changes package
- Functionality -c option: if comment to be deleted is the last in the line replace
  new line by space character. This is done to avoid errors or unintended line breaks
  from empty lines after deletion (which are interpreted as \par)
