[9fans] unexpectedly low pH in acid

[erik quanstrom]

in my last email, i wanted to put a comment after the dump(...) statement,
but it turns out that didn't work as expected.  the problem is simple enough:
acid // comments in acid mistakely consume the newline, leading to incorrect
line numbers, &c.

the fix for this is straightforward: after recognizing a // comment, continue
with newline processing:
