I=E2=80=99m just trying to phrase the documentation for bpchar so that the =
=E2=80=9Cbp=E2=80=9D,
which stands for =E2=80=9Cblank-padded=E2=80=9D, is justified.  The generic=
 term for the
trailing spaces here is padding in the noun sense.

I do understand the terminology confusion with the verb padding.  And see
why =E2=80=9Ctrimmed=E2=80=9D is actively confusing.  The prose probably ne=
eds to resolve
this - and technically does from what I=E2=80=99m reading.

You may wish to move on from critiquing my suggested changes and instead
propose something concrete of your own.  Provide a third choice besides
status-quo and my option.

Though I=E2=80=99m doubtful there is a nice precise hyphenated word to be f=
ound
here for =E2=80=9Ctreats any trailing spaces as being semantically insignif=
icant=E2=80=9D.
