Details:
This report applies to groff 1.22.3. The same issue exists in the latest
groff in git.
The .ta section of the info manual states, "The start-up value of [.ta in]
`gtroff' is `T 0.8i'."
However, this is not what groff itself reports:
$ echo '.tm \n[.tabs]' | groff -T ps
T36000u
$
Since the ps device has a resolution of 72000 units per inch, 36000u
corresponds to 0.5i, not 0.8i.
I don't know which value is correct, only that they don't agree.
