jsh 1.2.1 fixes two minor bugs in the v1.2.0 release below:

• Makefile fix for Mac OS X (defined empty variable)
• source built_in bugfix allowing parsing of a file with jsh alias expansion

jsh 1.2.0 introduces some awesome new features on the user interface side: ;-)

• Major new feature: context-sensitive custom GNU readline completion:
• built_ins, aliases and a number of predefined UNIX commands
• some custom completion for some specific UNIX commands: git, apt-get, make, jsh, ...
• wrote a dialog based sh installer shell script, as discussed in issue #55
• added a jsh_logout file, containing shell commands to be executed at logout of an interactive session
• a new source built_in to interpret a given file line per line
• fixed the ugly EOF (^D) exiting by outputting an extra newline iff EOF

This release also includes some work on the more technical side:

• Makefile enhancements:
  • now automatically builds a version string, containing info of the machine
  • auto-generate a man page with the filled in version number and data (using sed)
  • added a make release target for making releases with a release version string
  • various compile flags used by the installer
• alias bugfix allowing redefinition of an alias
• partially started the source code re-organizing into cohesive modules, as discussed in issue #46

Format string vulnerability patch for the v1.1.0 release.

Details: applied a format string vulnerability patch to the parsestream functions; passing printf may introduce format string vulnerabilities; one should pass the helper function printf_verbatim instead

A minor improvement to the first stable jsh release: added a --version option to query the current version number.

The first stable jsh release!
