man pages in many -doc packages are not rendering correctly

Hello, I was encouraged to submit a bug about this.

Many man pages from *-doc packages are not rending correctly, e.g. here is some sample output of man udisksctl from udisks2-doc:

UDISKSCTL(1)                     User Commands                    UDISKSCTL(1)








  .SH "NAME" udisksctl - The udisks command line tool


  .SH "SYNOPSIS"

    .HP 240u

      uuddiisskkssccttll
       status



    .HP 240u

      uuddiisskkssccttll
       info
       {
         | --object-path _O_B_J_E_C_T
         | --block-device _D_E_V_I_C_E
         | --drive _D_R_I_V_E
      }



    .HP 240u

      uuddiisskkssccttll
       mount
       {
         | --object-path _O_B_J_E_C_T
         | --block-device _D_E_V_I_C_E
      }
       [
         | --filesystem-type _T_Y_P_E
      ]
       [--options _O_P_T_I_O_N_S...]
       [--no-user-interaction]
