# check contents of /usr/share/terminfo, if present.
#
# 0. /usr/share/terminfo may only contain directories (not files). This
#    gets checked in 05-basic_sanity, not here.
# 1. directories under /usr/share/terminfo must have one-character names,
#    /a-zA-Z0-9/.
# 2. directories under /usr/share/terminfo mode 0755.
# 3. /usr/share/terminfo/*/ must contain only files (no subdirs).
# 4. files must go in the subdir for the first letter of their name.
# 5. files must be valid compiled terminfo entries.
# 6. files must be mode 0644 or 0444.
# 7. all files and dirs must be owned by root:root.
#
# Note: although I've never seen it done, it's perfectly legit for a
# terminfo file to have a space in its name. So that's not checked
# for here.
