[PATCH v2 07/11] t9903: move prompt tests to a new lib-prompt-tests.sh file

[Richard Hansen <rhansen@bbn.com>]

This is a step toward creating a new test script that runs the same
prompt tests as t9903 but with Zsh instead of Bash.

+# To use this library:
+#   1. set the variable shellname to the name of the shell (e.g.,
+#      "Bash")
+#   2. define functions named ps1_expansion_enable and
+#      ps1_expansion_disable that, upon return, guarantee that the
+#      shell will and will not (respectively) perform parameter
+#      expansion on PS1, if supported by the shell.  If it is not
+#      possible to configure the shell to disable (enable) PS1
+#      expansion, ps1_expansion_enable should simply return 0
+#      (non-zero) and ps1_expansion_disable should simply return
+#      non-zero (0)
+#   3. define a function named set_ps1_format_vars that sets the
+#      variables c_red, c_green, c_lblue, and c_clear to the strings
+#      that __git_ps1 uses to add color to the prompt.  The values of
+#      these variables are used in the first argument to the printf
+#      command, so they must be escaped appropriately.
+#   4. source this library
+
+# sanity checks
