\Here is my problem:
\ I have a file composed of multi-line records.
\ Continuation lines begin with arbitrary white space.
\ I want to extract *some* of the records.
\for example:
\ In this file, the "Here is my..." and "for example" lines
\ begin multi-line records. Suppose the records I want
\ are those that begin with an uppercase letter ("Here...")
\ sed -n -e '/^[A-Z]/,/^[^(spc)(tab)]/p' file
\ will print each such record, but would also get the "for..."
\ line of the second record.
\ sed -n -e '/^[A-Z]/,/^[(spc)(tab)]/p' file
\ will not get "for..." but will only get the first following
\ line that begins with white space.
#! /bin/sh
exec sed -n -e '

/^[ ]/b loop
