Portability fixes and various cleanups in wrapper scripts:

+ Fix the tests at the header of wrappers.  which(1) doesn't behave as 
  expected on some systems.  We should only assume that it's pretty widely 
  available (for example, it's a builtin in csh) and we should only rely on 
  its exit code by ignoring its output.
+ Replace 'echo -n' with 'printf' as the latter is recommended.
+ In markdown2pdf script, '--suffix' and '--backup' options of mv(1) appear 
  to be GNU-ism.  Apply a workaround.
+ Wrap some long lines to fit in an 80-column screen.
+ Remove spaces at the line ends.
