  3) You could try compiling MC with a different screen library. You

  is reputedly better at dealing with broken terminfo entries than
  Ncurses, and MC uses Slang by default.  But I suppose Ncurses might
  be better in some circumstances.

That's because

        a) slang used to supply hardcoded defaults to match rxvt if some
           information was missing (actually there were also some
           hardcoded defaults for a few other terminals, but rxvt was the
           target).  Most of that was removed early in the 1.4.x series.

        b) slang doesn't use some capabilities that ncurses does (this
           is especially noticeable in the way it clears trailing blanks
           on a line).

  That was my situation. My SSH client for OS/2 claims to provide a
  "substantial subset" of the xterm-color terminal.  It doesn't say
  which version of xterm-color. I doubt if even the various Linux
  distributions all provide exactly the same terminfo files.  None of

that's true (I haven't found much use in the distributions' customizations)

Some tips, in no particular order:

  The escape character is often represented by "^[", but Terminfo
  entries use "\E" and MC uses "\e".

tic recognizes either case

  Each terminfo capability has a short name and a long name that is
  easier to understand.  Unfortunately, 'tack' and 'tput' only use the
  short forms.  Keep a list handy for reference.

I hadn't noticed that (to-do list...)
