Sorry, I should have included those too.  Here they are:

--------------
CONFIG.SYS

REM Tip:  Put the real-mode driver for your CD-ROM in here.
REM It won't be used by Windows 95, but it will be used if you
REM choose "Restart your computer in MS-DOS mode" from
REM the Shutdown menu in Windows or if you choose F8 and select
REM one of the Startup menu options that let you enter into MS-DOS
REM instead of loading the Windows 95 GUI.
REM 
REM Be sure the information following the /D switch on the CD-ROM
REM driver matches the information following the /d: parameter on
REM MSCDEX loaded in Autoexec.bat.

That is consistent with bash running correctly when I boot directly to
DOS, since Windows 95's DPMI server wouldn't be running then.

Thank you again, Eli, for looking at this.
