a2f9188418 mbyte: Fix PVS/V557: do not do useless job 
I do not see how array overrun is actually possible, but still EUC encodings may 
do fine without a cycle.

24ee261317 if_cscope: Fix PVS/V560: condition would result in earlier return 
Previous block just checks for totmatches being zero and returns if it is. And 
totmatches is unsigned, so `totmatches > 0` may never be true.

103be37f42 ex_cmds: Fix PVS/V557: possible array overrun in :ascii 
Some calculation show that with the current setup there will not be enough bytes
occupied for that, barring the case of malicious translation. Still should be
possible to have array overrun with specially crafted translation.

db7f80302b ex_cmds: Remove #ifdef USE_GUI 
`ag` shows that this identifier (`USE_GUI`) is found in exactly one place (zero 
after this commit). So I assume macros is never defined.

f8d574225b eval: Silence PVS/V547: E882 may be triggered 
I failed to deduce why analyzer thinks E882 may not be triggered, though 
conditions for triggering it are strange: it would trigger E882 only in the 
single case “function returned non-number”. Cases “function thrown exception”, 
or “built-in sorter encountered error” will neither yield E882 nor stop 
sort()/uniq().

Note though that searching test code revealed that neither E702 nor E882 are not 
tested anywhere.

6f19b9f4e1 eval: Silence PVS/V614: use of potentially uninitialized pointer 
It is hard to say whether it actually is uninitialized, need to go deeper into 
regex code. Probably analyzer did not go that far as regmatch for sure would not 
be initialized up until calling NFA/DFA engine functions, which is to be done by 
pointer.

93be2ba542 charset: Fix transchar() with multibyte characters 
It appears that transchar() was working under assumption that 
`transchar_nonprint()` may be used for multibyte characters while its 
documentation stated exact opposite. It was not actually untrue though, except 
that longer buffer would be needed then the one stated in documentation. But it 
is false now with assert().

5660482406 api/buffer: Fix PVS/V547: use correct border for lnum 
Should actually be silencing that for the sake of the case when `long` is 
actually not 64-bit. But it appears that Vim had already defined maximal line 
number. And even declared that exact value invalid, so no need in silencing.
