[PATCH] [MAN] rename sh to dash, update DESCRIPTION and HISTORY

[Gerrit Pape <pape@xxxxxxxxxxx>]

Rename sh to dash in the header and synopsis; remove reference to the
4.4 BSD release in the description, and replace the history information
with a reference to NetBSD's ash.

Suggested by jaalto through
