			  X Window System Bug Report
			    xbugs@expo.lcs.mit.edu


VERSION:
    R4

CLIENT MACHINE and OPERATING SYSTEM:
    Sun 3/50, SunOS 3.4, cc or gcc compiled.

DISPLAY TYPE:
    N/A (Sun bwtwo)

WINDOW MANAGER:
    N/A (twm or gwm)

AREA:
    xrdb

SYNOPSIS:
    xrdb no longer strips trailing whitespace on resources

DESCRIPTION:
    Under R3, trailing whitespace after a resource value was stripped off.
    Now, under R4 it is maintained, which makes things like font string
    matches much more difficult.

    I am fully prepared to hear "This is a bug, not a feature, how else
    could you pass the string 'gronk<tab><space><tab>' ?!"  If so, might
    I suggest quotes?  If not, see fix below.

REPEAT BY:
    xrdb -load < .Xres

    Where .Xres contains say:

	xterm*VT100.font:myfont      /* I like to put comments here */

    And the font name ends up as "myfont    ".

SAMPLE FIX:
    I put back the trailing space stripper from R3:
