Dunno. Buglet or defectlet? Looks a feature, now, and it is too late
for an incompatible change :-)

In your workaround, you don't have a wildcard in the argument. Anyway,
a slightly better workaround which includes more information is to
search for "= ", as in
$ pipe sh log decw$incl*/table=* | search sys$pipe  "= "
  "DECW$INCLUDE" = "SYS$SYSROOT:[DECW$INCLUDE]"
        = "SYS$SYSROOT:[DECW$INCLUDE.EXTENSIONS]"
        = "SYS$SYSROOT:[DECW$INCLUDE.ICE]"
        = "SYS$SYSROOT:[DECW$INCLUDE.SM]"
$

VMS search uses RFAs to display a window which goes back as in /
window=(2,0). Unfortunately sys$pipe doesn't support RFAs. But if you
have GNV or a GNU grep on your system you may want to use:
$ pipe sh log decw$incl*/table=* | mc psx$root:[bin]grep "-iB2" "= "
(DECW$LOGICAL_NAMES)

  "DECW$INCLUDE" = "SYS$SYSROOT:[DECW$INCLUDE]"
        = "SYS$SYSROOT:[DECW$INCLUDE.EXTENSIONS]"
        = "SYS$SYSROOT:[DECW$INCLUDE.ICE]"
        = "SYS$SYSROOT:[DECW$INCLUDE.SM]"
$

Is that "all the information" you are looking for?
