Subject: Various fixes in markdown2pdf.

+ Add a trailing ':' to TEXTINPUTS as per the instruction in TeX FAQ:
    http://www.tex.ac.uk/cgi-bin/texfaq2html?label=graphicspath
  In the lack of it, pdflatex silently fails, for example, with the
  following command: 'TEXINPUTS=/tmp markdown2pdf'
+ Put the origdir at the front for the correct directory search order.
+ pdflatex didn't create log file on one occasion (the above command) that
  made sed commands failed.  Test the existence of log before filtering it.
+ A few non-essential changes.
