Copy doesn't recognize \. except on its own line

[dclements]

The copy command doesn't recognize the presence of the \. message except when it is on its own line, with no whitespace or other characters before or after:

test > copy test from stdin
reading row data until "\."

test > 1,1\.
test > \.
inserted 0 row(s)

test > copy test from stdin
reading row data until "\."

test > 2,1
test >  \.
test > \.
inserted 1 row(s)

test > copy test from stdin
reading row data until "\."

test > 3,1
test > \. 
test > \.
inserted 1 row(s)

Expected would be for it to read until it hits those characters, trimming any excess whitespace and being usable at the end of a line, rather than just on its own.

The silent failure of lines is another problem covered by Issue #25 and Issue #27.
