[Bug gas/3856] New: irpc skips all but first space in quoted string

[jcomeau at unternet dot net]

iterating using .irpc over a string such as "xxx   xxx" is identical to
iterating over "xxxxxx". only if the first character is a space will irpc see
it: " xxx xxx"
will be processed as " xxxxxx". this bug surfaced when attempting to write a
macro to assemble character maps:

$ less chars.lst
   1                    ;# compile character map from data stored as "######
   ###"
   2                    ;# the above should compile to the two bytes 0xfc 0x03
   3                    .macro CHR16X24 row
   4                     .equ packed, 0
   5                     .irpc pixel, "\row"
   6                      .equ packed, packed << 1
   7                      .ifeqs "\pixel", "#"
   8                       .equ packed, packed | 1
   9                      .endif
  10                     .endr
  11                     .byte packed >> 8, packed & 0xff
  12                    .endm
  13 0000 0003          CHR16X24 " ##             "
  14 0002 03FF          CHR16X24 "###   #######   "
  15 0004 3FFF          CHR16X24 "#### ########## "
  16 0006 FFFF          CHR16X24 "################"
DEFINED SYMBOLS
                            *ABS*:00000000 fake

NO UNDEFINED SYMBOLS
chars.lst (END)

if this is expected behavior, then the texinfo file should reflect that, instead
of stating: "For each character in VALUE, SYMBOL is set to the character, and
the sequence of statements is assembled." (under .irpc)

the spaces aren't getting preprocessed out; inserting an '.ascii "\row"'
statement into the above macro shows the correct string in all cases.

this may already be fixed in a later version, or on other platforms than Cygwin.
