The following is a nice little function I use in my Eshell prompt. It
shortens the name of all the parent directories of the current one in its
path, but leaves the current one written in full. It also abbreviates the
equivalent of the ~$HOME~ (~/home/<username>/~) directory to a simple =~=.

"Abbreviate `$path'. If `$abbreviate' is `t', then all parent
directories of the current directory will be abbreviated to one
letter only. If a parent directory is a hidden directory (i.e.
preceeded by a dot), the directory will be abbreviated to the dot
plus the first letter of the name of the directory (e.g.
\".config\" -> \".c\").
For public use of the function, `$path' should be a string
representing a UNIX path. For internal use, `$path' can also be a
list. If `$path' is neither of those, an error will be thrown by
the function."
