Actually that's quite a good example for how such output *could* be
helpful if users didn't ignore it ;-) 'R' reloads the file, 'r' scrolls
the page to the right ...

Some of these messages about failed navigation are only enabled in the
Xaw version which has very little visual feedback by default.  Current
users are probably more accustomed to 'responsive' GUIs, and annoyed
by these messages. I should probably disable those that can occur
during normal page navigation.

You can disable those messages with '-hushstdout' (see the man
page for details).

Hmm, there's also a '-hush' option that suppresses all warnings,
but doesn't affect the statusline messages; it probably should,
I'll change that.

Maybe there could be a 'hushbell' option to disable the beeps ...
beeping still seems common in programs like eg. xpdf and acroread
which both eg. beep when trying to go to the previous page at the
first page of a document, so I'd say it's a reasonable default.

Best,
Stefan
