 Module Name:   src
 Committed By:  snj
 Date:          Fri Dec 18 06:06:56 UTC 2009
 Modified Files:
        src/usr.bin/less/less [netbsd-5]: cmdbuf.c
 Log Message:
 Pull up following revision(s) (requested by dholland in ticket #1194):
        usr.bin/less/less/cmdbuf.c: revision 1.8
 Don't attempt to read or write ~/.lesshst if it's not a regular file
 or a symlink to a regular file. Previously, symlinking to /dev/null
 would cause less to trash /dev/null if run with sufficient privileges,
 as seen in PR misc/42237.
 While the official way to disable .lesshst is to set an environment
 variable, that is problematic in some cases, such as single-user mode.
 A safer way to prevent even an unpatched less from writing anything
 out is to mkdir ~/.lesshst.
 To generate a diff of this commit:
