[PATCH] script: Do not allow a delimiter between function name and block start.

[Glenn Washburn]

Currently the following is valid syntax, but should be a syntax error:

grub> function f; { echo HERE; }
grub> f
HERE

This fix is not backward compatible, but current syntax is not documented
either and has no functional value. So any scripts with this unintended
syntax are technically syntactically incorrect and should not be relying
on this behavior.

Did you test the 32-bit and 64-bit builds with this patch?

I have tested that this patch does indeed compile on i386-pc and
x86_64-efi. Is that what you're wondering?  Is the patch not compiling
for you?

You can verify that these are all issues by solely applying the patch
to include/grub/err.h and building under a variety of target arches and
platforms.

I notice now that both 32-bit and 64-bit builds will fail with this
patch applied to master.  This patch assumes some code changes in my
patch titled "luks2: Fix use of incorrect index and some grub_error()
messages." that has been sent to this list and changes from another
patch I forgot to include.  I'll resend the patch with the changes from
the missing patch, but still require changes from the previously
mentioned patch sent to the list.

Fix the many issues this uncovered mostly related to incorrect length
modifiers.

[PATCH v2 0/2] error: Do compile-time format string checking on grub_error.

[Glenn Washburn]

I've separated this into two patches from the previous one, but nothing else
has changed (except the commit message). I think at least the first patch should
be applied. Since I don't have a setup to test every architecture+platform
build of grub, I can't gaurantee that the second patch won't cause a build error
on some other architecture+platform combo. However, if it does, I'll bet it'll
get fixed quickly.  However, for that reason, I suggest the second patch be
applied after the 2.06 release (might be moot at this point). This series has
successfully built for me for i386-pc and x86_64-efi.

[PATCH v2 1/2] error: Fix issues mostly related to incorrect length modifiers in calls to grub_error().

[Glenn Washburn]

The issues fixed here do not produce crashes that I'm aware of. However,
they do fix unintended error string output.

[PATCH v2 2/2] error: Do compile-time format string checking on grub_error.

[Glenn Washburn]

This should prevent the current situation where there were many format
string errors found and thus improve the quality of error reporting.
