seekg and failbit

[Jean-Marc Bourguet]

Hi all,

basic_istream::seekg has two versions, one taking a pos_type, the other taking a off_type and a seekdir.

The first is defined to clear the eofbit before constructing the sentry. The second isn't.  Does someone knows
why?

AFAIK, the discrepancy has been added when fixing library issue 60, which refers to n1219. But if I've missed the rationale
for the difference if it was present at one of those places.

Yours,

A likely reason is that the change was applied only once, instead of for
both versions of seekg.

There is a new library issue #2244 proposing that this should be fixed:

Thanks.  I looked for a rationale and forgot to look if somebody else had brought it up as an issue.
