dashes in field names are always converted to underscores about gcfg HOT 3 CLOSED

Thanks for the report, but I can't reproduce the issue. Actually there is an 
example in the docs showing that dashes specified in tags work: 
http://godoc.org/code.google.com/p/gcfg#example-ReadStringInto--Tags

Can you share a runnable code sample that demonstrates the error?

While the readability of the code could be improved, the '-' => '_' 
substitution only matters for fields where there is no name specified in a tag.

I just tried to reproduce the error I got yesterday and I can't seem to get it 
to fail any more :/
I did update the package before I tested, so maybe it was fixed?

In any case, this issue can be closed.
Thanks for your time!

I didn't go through the diffs in detail but I don't recall any relevant changes 
(unless you were using a version prior to tags support). At least the 
example-test has been there since the initial implementation. What occurred to 
me is that the error could happen if the field is not exported, but that is to 
be expected.

Anyway feel free to reopen in case you encounter it again.
