This is a repeat of bug #57366 which was closed improperly. ispell/aspell only checks html files up to the first bare &: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> </head> <body text="#000000" bgcolor="#FFFFFF" link="#0000EE" vlink="#551A8B" alink="#FF0000"> <P>A rail trail & asdfpioasudfoipasdufopasd. </body> </html> The spelling error, and entity error, will never be noticed. Note that ispell is also missing a man page.
