There's more data in termcap than that (which some people would like to use=
).
And there's additional data for terminfo -- again, some want it.
man infocmp:
For best results when converting to termcap format, you should use b=
oth
-C and -r. Normally a termcap description is limited to 1023 byt=
es.
infocmp trims away less essential parts to make it fit. If you =
are
converting to one of the (rare) termcap implementations which accept=
an
unlimited size of termcap, you may want to add the -T option. More =
of=E2=80=90
ten however, you must help the termcap implementation, and trim exc=
ess
whitespace (use the -0 option for that).
(-T is appropriate here - ymmv)
With -C alone, I get
